Teams win RINGS, not single players.
The Lakers were 25-7 without Kobe during their 3peat run.
The Lakers were a .500 team without Shaq in that time period when missed roughly the same amount of time.
The Lakers were terrible without Shaq once he left. Kobe couldn't lead them to a .500 record.
Kobe threatened to leave unless he got another All Star big man in the middle.
Since all else has failed, I see no reason for the Knicks not to sign Allen Iverson.
